[Boost-build] detecting MS runtime library version

Hi,

I'm new to using Jam and Boost.Build, so I hope this is not a dumb question.

It appears that Boost.Build detects, to a certain extent, the
Microsoft compiler that is installed and generates the appropriate
output directories. For example, using MSVC++ Express 2005, I get
bin\msvc-8.0express\debug and bin\msvc-8.0express\release. My question
is, shouldn't the actual runtime library version be checked and used
to specify the output directory? For example, I believe that the pre
SP1 toolchain links against MSVCRT 8.0.50727.42, while SP1 links
against 8.0.50727.762.  I think it is true that you can't mix
libraries and executables between the two. Shouldn't Boost.Build
create output directories that differentiate between the two?

It appears that recent releases of the compiler sort of indicate the
library version in the compiler version. For example, the 2005 SP1
compiler is version 14.00.50727.762. The last two fields in the
compiler version match the last two fields in the runtime lib version.

Thanks,
